Resolution: Medical MRI resolution is typically about 1 mm; the desired resolution of MRM is 100 μm or smaller to 10 μm, comparable with histology. Specimen size: Medical MRI machines are designed so that a patient may fit inside. MRM chambers are usually small, typically less than 1 cm 3 for the imaging of rats, mice and rodents. BrukerBio ...
MRI has the advantages of having very high spatial resolution and is very adept at morphological imaging and functional imaging. MRI does have several disadvantages though. First, MRI has a sensitivity of around 10 −3 mol/L to 10 −5 mol/L, which, compared to other types of imaging, can be very limiting. This problem stems from the fact that ...
DermAtlas is an open-access website devoted to dermatology that is hosted by Johns Hopkins University's Bernard A. Cohen and Christoph U. Lehmann. Its goal is to build a large-high-quality dermatologic atlas, a database of images of skin conditions, and it encourages its users to submit their dermatology images and links for inclusion.
Cancer research: Micro-MRI is often used to image the brain because of its ability to non-invasively penetrate the skull. Because of its high resolution, micro-MRI can also detect early small-sized tumors. Antibody-bound paramagnetic nanoparticles can also be used to increase resolution and to visualize molecular expression in the system. [2]
Amplified magnetic resonance imaging (aMRI) [1] [2] is an MRI method that is coupled with video magnification processing methods [3] [4] to amplify the subtle spatial variations in MRI scans and to enable better visualization of tissue motion. aMRI can enable better visualization of tissue motion to aid the in vivo assessment of the biomechanical response in pathology.
Here is a list of dermatologic disorders on Wikipedia that would benefit from additional clinical images. Amelanotic melanoma - a single image of a canine lesion; Pemphigus vulgaris - single clinical image; Bullous pemphigoid- single clinical image; Urticarial vasculitis- no clinical images; Chloracne- single image (not very helpful)
[27] [28] The result of an MRE scan is a quantitative 3-D map of the tissue stiffness, as well as a conventional 3-D MRI image. One strength of MRE is the resulting 3-D elasticity map, which can cover an entire organ. [2] Because MRI is not limited by air or bone, it can access some tissues ultrasound cannot, notably the brain.
Diffusion imaging is an MRI method that produces in vivo magnetic resonance images of biological tissues sensitized with the local characteristics of molecular diffusion, generally water (but other moieties can also be investigated using MR spectroscopic approaches). [15] MRI can be made sensitive to the motion of molecules.
